The Yo-yo Moon Capture Hypothesis I hope you all have played with a yo-yo and know how it works, how the stored rotational momentum enables it to climb up the string again. I am going to show how this principle can be proposed as an alternative method to Moon formation as opposed to the widely accepted Giant Impact Theory. I have written up the proposal on another forum, but I will paste and modify posts from there and modify them so they will not be the same. If there are any questions or discussion this thread will have a life of its own. I am combining the Moon capture (the Yo-yo Moon Capture Hypothesis) with the "Compressed Earth" theory: http://www.physforum.com/index.php?act=Post&CODE=06&f=27&t=29842&p=602331 from around that post and onward. It is a very interesting idea and seems to have lots of support for it as I will show.
